With Gutenslider it is very intuitive and easy to change the focal point of your slides. That way you can increase users attraction to your slides by putting focus on the really important parts of an image or video.
Just click the edit button and then set the focal point of each individual slide to your need. Also notice that you might want to style gutenslider first to your needs (e.g. full width image slider) and then set the focal point for best results.
